LAMP-OPERATING- MECHANISM.

Specification of Letters Patent.

Application filed August 1. 1919. Serial No. 314,608.

To all whom it may concern Be it known that I, ARNOLD H. BAESE- MANN, a citizen of the United States, and

resident of Rib Falls, in the county of Marathon and State of Wisconsin, have invented certain new and useful Improvements in Lamp Operating Mechanism; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in lamps or similar fluid fuel burners of the wick type. 1 p It is primarily the object of my invention to provide an arrangement for most readlly igniting and extinguishing the lamp or burner, and it is more particularly my ob ect to provide an operating mechanism of this character associated with a lamp whereby the lamp may be lighted and extinguished without removing the chimney, and without the necessity of a manual blowing action.

A further and more specific object resides in the provision of means for'igniting the lamp or burner wick by a spark struck from a body of pyrophorous metal or other spark v forming material disposed adjacent the wick. I

A still further object resides inv the provision of a device for closing off or snufling a c lindrical lamp wick.

still further object resides in the provision of a simple and compact mechanism for the purpose described which may be readily and economically associated with a lamp structure, particularly of the center draft type. 7

With the above and other objects and advantages in view, my invention resides more particularly in the novel combination, formation and arrangement of parts hereinafter described and particularly pointed out in the appended claims. 7

In the accompanying drawings: Figure 1 is a side elevational view of a center draft oil lamp structure showing my improved lighting and extinguishing mechanism associated therewith.

Fig. 2 is a sectional View on the line 2-2 of Fig.1;and I c Fig. 3 is a detail sectional view. on the line 33 of Fig. 2.

Referring now more particularly to the drawings, there is shown an. oil lamp comprising the reservoir body-lO carrylng the central upstanding wick drum 11 in which is disposed the usual center draft foraminous cylinder 12, the usual wick 13 being disposed'between the wick drum and this cyl-- inder.

My improved lighting mechanism includes a sparking unit of conventional na ture including a tubular support 14 upstanding from the top ofthe reservoir adjacent the wick drum 11, opposite sides of the upper portion of the support being cut away to provide clearance for a sparking wheel 15 Patented June 28, 1 921 journaled therein and carrying an outstandr ing lever arm 16. A body of pyrophorous metal 17 is mounted in a restricted portion of, the tubular support above the wheel 17 and is resiliently urged against the wheel by a hook bar 18, having its lower end extended past the wheel and connected witha common spring 19 housed within the lower portion of the tubular support, said spring being also connected with the wheel, whereby the wheel is urged to rotation in one di rection, its degreeof rotating movement being limited by engagement of the lever arm 16 with a pin 20 on the bar 18. A reservoir 21 for volatile fuel liquid, such as alcohol, is disposed on the reservoir 10, and carriesan upstanding slotted neck 22 in whichis slid ably mounted a sleeve 23 carrying a wick 24, the wick being normally housed within the neck 22, which is closed by a hinged cover 25. The sleeve 23 carries a tongue 26' ignition. by reason of the volatile nature of the fuel of said wick 24, and this ignition. will spread to the slower lamp wick 13 to effect the normal lighting of the lamp. The various movements necessary in this operation are effected by a lever 27 intermediately pivoted on the lower portion of the support tube 14, and having one end bifurcated to straddle the stem .28 of a push button 29 which is urged upwardly by a spring 30 coiled on said stem. The other end'of the lever 27 is pivotally connected with a link 31 which is in turn pivoted to the wick sleeve 23. A pawl rod 32 is pivoted to the end portion of the lever 27 adjacent the push button, and this pawl rod extends upwardly through a bracket arm 33 outstanding from the support 14 and terminates in a hook engageable with the lever. arm 16of predetermined degree of downward movement by a cam enlargement 35 on said pawl rod engageable with the bracket arm, this disengagement freeing the sparking'wheel and permitting the same to rotate under influence of its springto direct sparks against theivolatile wick.

The wick of the lamp may thus be lighted by simply depressing the push button 29 which rocks the lever 27 to simultaneously store rotating energy for the sparking wheel 15, and-raise the volatile fuel wick 24 to operative position, the sparking wheel being released at the time that the wick 24 is raised, and the push button 29 is momentarily held in lowered position to permit spreading of the flame from the volatile fuel wick 24 to the lampwick13, and this lighting action may be repeated indefinitely, since all of the parts a-re reset upon releasing the push button 29, the hooked upperend of the pawl rod 32 having cam contact with thelever arm 16 in upward movement of saidpawl rod to procure its engagement with the lever arm. The volatile fuel wick is extinguished as the mechanism is reset by the closing movement of the cover 24 of the wick neck 22.

For extinguishing the lamp wick 13, a sleeve 36 of very'light resilient metal is slidably disposed about the wick drum 1'1 and has a-series of tapered tongues 37 at its upper sides which are adapted to spring inwardly with their side edges in contact relation'to close off the wick when said tongues are raised thereabove. The'wick is shielded from engagement by these tongues in their closing action by upstanding spurs 39 on the upper edge of the wick drum 11; This extinguishing sleeve 36 is operated by a spanner lever 40 pivoted'on' a bracket arm 41 carried by the lower portion of the wick drum 11,.one bifurcated end of this lever embracing and having pin and slot connection with the sleeve 36, while its other bifurcated end embraces a stem 42 of a push button 43 which is mounted on and resiliently urged upward from the lamp reservoir 10 by a spring 44 coiled on said stem. The lamp may thus be extinguished by simply pressing the push button 43 to close off or snuff the wick. p

By the foregoing constructionI have provided means for lighting and extinguishing the wick of. a lame without the neces sity of removing the c imney. and while I have herein shown and described a preferred embodiment of my invention, it will be appreciated that various changes and modification of structure and arrangement may be employed "to meet different conditions of use and manufacture without departing in any manner from the spirit of my invention. I

What is claimed is:

1. The combination with a burner, of a 7 portion, a wick slidable in said neck portion and movable therefrom to a position adapted to transmit flame to. the burner, sparking mechanism including a movable sparking member yieldingly urged in direction of'sparking movement, means for moving the volatile fuel wick from said receptacle neck, means actuated by said last named means for moving said sparking member in opposition to its yielding memher, and means for. releasing said sparking member near the end of said Wick movement. p V

2. The combination with a burner, of a receptacle for volatile'fuel including a neck portion, a wick slidable in said neck portion and movable therefrom to a position adapted to transmit flame to the burner, an inter mediately pivoted lever, a link connection between one end portion ofrsaid lever and the volatile fuel wick, a pawl bar connected with the other end of said lever and engaging with the spark memberv to move it in opposite direction, and means for procur-- ing disen agement of said pawl bar from the sparkmg member upon continued rocking movementof the lever. V i

3. The'combination with a burner, of a receptacle for volatile fuel includinga neck portion, a wick slidable in said neck portion, means for projecting said wick from the neck portion, a sparking member for directing sparks toward said neck, a spring for controlling the same,means actuated by said 105 wick "projecting means for setting said sparking member in opposition'to the spring during the first part of said projecting movement,-and means for releasing it during the latter part of said movement.

4. The combination with a burner, of a receptacle for volatile fuel including a neck portion, a wick slidable in said neck portion and movable therefrom toa position adapted to transmit fiamejto the burner, a 115 spring held sparkingmember, an interme-i' diately pivotedspringheld lever, means con 7 nected with one end of theilever for ad vancing the wick when said lever is moved against the tensionof thespring'andmeans 12 connected with .the'other end of said lever for first moving the sparking member against the tension of its spring'and then] releasing it.

5. The combination witha' burner, of a member yieldingly urged in the direction of sparking movement, an interinediately pivoted lever, a link connection between one end portion of said lever and the volatile fuel Wick, a pawl bar connected with the other end of said lever and engaging with the sparking member to move it in opposition to its spring, and means for disengaging said pawl bar from the sparking member upon continued rocking movement of the lever.
